Sirius could help Harry cope by sharing his own experiences of being an outcast in his family. He could tell Harry that just because his parents did this horrible thing, it doesn't mean he's unlovable. Sirius could also introduce Harry to his friends in the wizarding world, like Remus, who could also offer support and friendship.
Sirius often provides emotional support to Harry in fanfics. Since Harry has lost his parents, Sirius, being his godfather, fills that parental role to some extent. He might share stories about Harry's father, which gives Harry a sense of connection and pride. Also, Sirius's skills as a wizard, like his combat abilities, can be used to train Harry or defend him when he's in danger.
In some fanfictions, Ginny might use her love and emotional support to help Harry heal. She could be there for him, listen to his problems, and give him a sense of normalcy. Sirius, on the other hand, might share his own experiences of dealing with dark magic and trauma. He could teach Harry how to better protect his mind from the after - effects of his battles, like using Occlumency in a more effective way.
Some fanfictions make Neville OP by changing his backstory. Maybe he was secretly trained by a powerful wizard in his childhood, and this hidden training surfaces during his time at Hogwarts, allowing him to outperform his peers and take on challenges that would be impossible for the regular Neville. This gives him an edge and makes him an OP character in the fanfiction world.
In some fanfics, Snape might help by using his knowledge of the situation. He could provide crucial information that clears Harry's name. Maybe he has some insights into Sirius' situation or the events that led to Remus blaming Harry that others don't have, and he decides to share that information to set things right.
In many of these fanfictions, Draco often starts as a more guarded character. But as Neville's pregnancy progresses, he becomes more protective and caring. For example, in 'The Unlikely Bond', he gradually sheds his Slytherin cold - exterior. Neville, on the other hand, grows in confidence. His pregnancy makes him more assertive about his relationship with Draco.
Their relationship would likely become more intimate and closer. With the pregnancy, they would have to rely on each other more. Neville might become more protective of Hannah.
Neville would likely have more self - discovery in terms of her femininity. She might start to embrace her true self more as the story progresses, becoming more confident in her identity.
In the fanfiction, it could develop through shared experiences. Maybe they both get involved in a dangerous situation in the Forbidden Forest. Draco is used to relying on his own wits, but Neville's kind heart and loyalty make him a valuable ally. As they fight off dark creatures together, they start to see each other in a new light. Draco begins to respect Neville's tenacity, and Neville sees that Draco is more than just a snobbish Slytherin.
